Pre-filtration filters on the outside of the unit Indoor work leads to an increased concentration of aspergillus. In order to protect the high effiency particulate air filter inside the unit during building activities, pre-filtration frames with filters are added to the outside of the device. The life-time of the high efficiency particulate air filter inside the unit is therefore largely extended. The prefilters are supplied in packages and are easily changed.
